How to bring up an 'unknown' TV-tuner card: Zogis RA220 TV-Tuner
I've got a Zogis Real Angel 220 RA220 TV-Tuner card.
http://www.zogis.com/main_products_s..._PCI_RA220.htm
In spite of what the box says, the card doesn't do all three analog TV standards: NTSC/PAL/SECAM. Zogis sells different versions for various parts of the world and uses the same box. I've got the NTSC version.
Unfortunately, it's not recognized by V4L. I get this message in dmesg:
# dmesg

saa7134: Congratulations! Your TV card vendor saved a few
saa7134: cents for a eeprom, thus your pci board has no
saa7134: subsystem ID and I can't identify it automatically
saa7134: </rant>
saa7134: I feel better now. Ok, here are the good news:
saa7134: You can use the card=<nr> insmod option to specify
saa7134: which board do you have. The list:
saa7134: card=0 -> UNKNOWN/GENERIC

Ran a script to test all the possible combos. Apparently it's necessary to cycle through rmmod/modprobe/watchTV to see if it works. Is there an easier way to find out? Here's the script:
test_all_saa7134_card_combos.sh
Code:
#/bin/sh
MAXCARD=144
MAXTUNER=69
for i in $(seq 0 $MAXCARD);
do
for j in $(seq 0 $MAXTUNER);
do
rmmod tuner saa7134
modprobe saa7134 card=$i tuner=$j
echo "Is TVtime working with card=" $i " and tuner=" $j " ? "
sleep 1 # make sure /dev/video is registered when tvtime starts
tvtime
done
done
I got lucky, after only doing a few hundred tests, "modprobe saa7134 card=3 tuner=0" worked. Many other tuner numbers worked too with card=3. Video and audio quality is good.
This is strange -- the video output doesn't appear on the 'Television' output -- but instead appears on 'Composite2' output. You can only tune channels by using 'Input Configuration', switching to a blue-screen 'Television' and then switching back to 'Composite' to view it.
There is no /dev/tuner. Should there be?
These messages appeared at each loop when doing the modprobe:
